Heroin (INN: diacetylmorphine, BAN: diamorphine) is a semi-synthetic opioid synthesized from morphine, a derivative of the opium poppy. The white crystalline form is commonly the hydrochloride salt diacetylmorphine hydrochloride. Upon crossing the blood-brain barrier, which occurs soon after introduction of the drug into the bloodstream, heroin is converted into monoacetylmorphine and morphine, the compounds that mimic the action of endorphins, creating a sense of extreme well-being with the feeling centered in the gut. Heroin affects the bodies Central Nervous System over stimulating the bodies creation of its own naturally occurring pain killers known as endorphins. Long term use can lead to intense physical dependence known as being SICK. Symptoms such as uncontrollable bowel functions, vomiting, sweating, and intense muscle aches, especially in the lower legs are common, and last acutely anywhere from 7 to 10 days. Acute withdrawal is followed by a feeling of lag where even the most common functions like brushing ones teeth is a chore. This lag can last months. A first time user takes longer to acquire a habit (addicted), than someone who has already been addicted. One of the most common methods of heroin use is via intravenous injection, although it may be smoked or snorted depending on purity. Heroin is commonly seen in two different forms, one: as a brown hard toffee like substance known as Black Tar, and two: as a white powder known as China White. The majority of black tar heroin comes from Mexico well the vast supply of the white powder commonly known as china white comes from Indochina.

A white, odorless, bitter crystalline compound, C17H17NO(C2H3O2)2, that is derived from morphine and is a highly addictive narcotic. Also called diacetylmorphine.

Illegal drug generally considered to be the worst, most addictive and dangerous of all the predominant recreational drugs.

A substance derived from the plant, poppy flower. Found in most regions of the world, and created in Southeast and Southwest Asia, Central America and the Mideast. Heroin comes in two forms, tar and china. Tar is usually made in Mexico, while the china (hence, "fine china") comes from the other sections of the world in many colors, shades, and cuts. There are many ways to use heroin, including intravenously- with a needle, smoking- using foil; "chasing the dragon", and snorting the substance. Many users each year overdose and die, relapse, get arrested, or stay addicted. Heroin is displayed to be a highly fashionable drug, but is not. Slang terms for heroin are: junk, dope, smack, shot, shit, h, etc.
The onset of a heroin "rush" from a needle is about 3-7 seconds, and lasts about 3 seconds.

Heroin is processed from morphine, a naturally occurring substance extracted from the seedpod of the Asian poppy plant. Heroin usually appears as a white or brown powder. Street names for heroin include "smack," "H," "skag," and "junk." Other names may refer to types of heroin produced in a specific geographical area, such as "Mexican black tar." Heroin abuse is associated with serious health conditions, including fatal overdose, spontaneous abortion, collapsed veins, and, particularly in users who inject the drug, infectious diseases, including HIV/AIDS and hepatitis.
The short-term effects of heroin abuse appear soon after a single dose and disappear in a few hours. After an injection of heroin, the user reports feeling a surge of euphoria ("rush") accompanied by a warm flushing of the skin, a dry mouth, and heavy extremities. Following this initial euphoria, the user goes "on the nod," an alternately wakeful and drowsy state. Mental functioning becomes clouded due to the depression of the central nervous system. Long-term effects of heroin appear after repeated use for some period of time. Chronic users may develop collapsed veins, infection of the heart lining and valves, abscesses, cellulitis, and liver disease. Pulmonary complications, including various types of pneumonia, may result from the poor health condition of the abuser, as well as from heroin’s depressing effects on respiration.
